Completeness of regional cancer registry data in Northwest Russia 2008-2017.

Background: A national framework for population-based cancer registration was established in Russia in the late 1990s. Data comparability and validity analyses found substantial differences across ten population-based cancer registries (PBCRs)in Northwest Russia, and only four out of ten met international standards. This study aimed to assess the completeness of the PBCR data of those registries.

On the application of a ZrO2-based solid electrolyte in isotope ratio mass spectrometry.

The application of a high-temperature electrochemical reactor based on stabilized zirconium dioxide (0.9 ZrO(2)0.1 Y(2)O(3)) for organic gas sampling in continuous-flow isotope-ratio mass spectrometry (CF-IRMS) has been found to be efficient.
